The aim was to describe levels, patterns and correlates of physical activity and sedentary behavior in a sample of Swedish children, two years of age, with normal weight, overweight and obese parents.
Data from 123 children, 37 with normal-weight parents and 86 with overweight/obese parents, enrolled in the Early Stockholm Obesity Prevention Project study was used. Children wore an Actigraph GT3X+ accelerometer for seven days. Average activity (counts per minute), number of steps and time spent in low and high-intensity physical activity and in sedentary was assessed. Differences between weekdays and weekend days were examined as were correlations with sex, body mass index (BMI), motor skills and family-related factors.
Children were active at high intensity 11% of the day. On average 55% of the day was spent being sedentary. Number of steps and time in low-intensity physical activity differed between weekdays and weekend days: on weekdays, 363 more steps (p = 0.01) and six more minutes in low physical activity (p = 0.04). No differences were found for any physical activity or sedentary behavior variable by sex, BMI, motor skills or any family-related variable (p = 0.07 - 0.95).
Two-year-old children have an intermittent activity pattern, that is almost similar on weekdays and they spend about half of the daytime active. The absence of any association with sex, BMI, motor skills or parental factors indicates that the individual variation in this age group is primarily due to endogenous factors.

目的是描述瑞典正常体重、超重及肥胖父母的两岁儿童样本中的身体活动和久坐行为水平、模式及其相关因素。
使用了参与早期斯德哥尔摩肥胖预防项目研究的123名儿童的数据，其中37名儿童的父母体重正常，86名儿童的父母超重/肥胖。儿童佩戴Actigraph GT3X+加速度计七天。评估平均活动量（每分钟计数）、步数以及在低强度和高强度身体活动及久坐状态下所花费的时间。研究了工作日和周末之间的差异，以及与性别、体重指数（BMI）、运动技能和家庭相关因素的相关性。
儿童一天中有11%的时间处于高强度活动状态。平均而言，一天中有55%的时间处于久坐状态。工作日和周末在步数以及低强度身体活动时间上存在差异：工作日步数多363步（p = 0.01），低强度身体活动时间多6分钟（p = 0.04）。在任何身体活动或久坐行为变量方面，未发现性别、BMI、运动技能或任何家庭相关变量之间存在差异（p = 0.07 - 0.95）。
两岁儿童具有间歇性活动模式，工作日几乎相似，且白天约一半时间处于活跃状态。未发现与性别、BMI、运动技能或父母因素存在任何关联，这表明该年龄组的个体差异主要归因于内源性因素。
